1 Claim. (Cl. 257-296) This invention relates to a building and air conditioning structure.

The object of the invention is to provide a novel and economical building and air conditioning structure embodying an outlet box of the type now on the market wherein a primary air stream is caused to flow therethrough, and the flow of primary air through nozzles or equivalents in the box causes the induction into the box of air from within the building to be mixed with the primary air and discharged into the building from the outlet box, and also embodying a cellular metal floor through selected cells of which the primary air stream is distributed to the outlet box.

With this general object in view and such others as may hereinafter appear, the invention consists in the building and air conditioning structure hereinafter described and particularly defined in the claim at the end of this specification.

In the drawings:

Fig. 1 is a perspective view of a sutficient portion of a building and air conditioning structure embodying the invention to enable the same to be understood; and

Fig. 2 is a perspective illustrating the reverse or rear side of the outlet or sill box shown in Fig. 1.

Referring to the drawings, in the structure illustrated in Fig. 1, 10 represents a pair of l-beams forming a part of the structural framework of a building and which, for example, may comprise two of the beams of the framework at a story of the building. The cellular metal load supporting floor indicated generally at 12 may comprise any of the known forms of cellular metal floor now on the market, such for example as that illustrated in the United States patent to Young, No. 1,867,433. Such cellular metal floor 12 is operatively supported on and preferably welded to the supporting beams 10 and arranged to extend across the top thereof. These cellular metal floors are customarily manufactured in unitary lengths and of standard widths embodying two or more cell structures 14, and such units are erected on the beams of the metal framework at each story of the building in side-byside relation and also with the units in end abutting relation so that continuous raceways or conduits are formed by the cells of the end abutting units. Inasmuch as the details of manufacture and of erection of such cellular metal floors are well known, further description thereof is believed to be unnecessary.

In accordance with the present invention provision is made for conducting a primary air stream up through a riser indicated at 15 from a source of supply of the primary air, and in practice such source of supply may comprise a blower located in the basement or at one of the stories of the building and by which air is forced up through the riser 15 and thence through a connecting duct 16 and led into one or more of the cells 14 of the floor so that air is caused to flow through the floor. Provision is made for conducting such air to a sill box 20 of known structure and which, as herein shown, comprises a housing arranged to fit over openings 22 in the upper surface of the cellular metal floor as more or less diagrammatically indicated in Fig. 1. The interior of the housing is provided with a restricted throat portion or nozzle 26 by which the primary air thus introduced to Within the base of the housing is caused to flow upwardly in an air stream of a nature such as to eifect the induction of secondary air from within the room or portion of the building at which the outlet is located, causing the secondary air to flow into the interior of the outlet box,

through louvers 27 and thus be mixed with the primary air stream.

lrovision is made for conditioning the secondary air by means of either heating or cooling coils 30 through which the heating or cooling medium may be circulated from a source of supply not shown. In this manner the air emerging from the outlet box through the upper or discharge end thereof will be conditioned by the extent to which the secondary air is cooled or heated. The structure of the outlet box per se forms no part of the present invention, and the utility flowing from the structure disclosed in Fig. 2 centers around the elimination of the usual space consuming duct work heretofore employed for conducting the primary air from the riser 15 to the sill or outlet box 20. In practice the riser 15 may be located in the usual service core of a multi-story building, and the connecting duct 16 may be extended in the usual corridor adjacent the service core so that maximum ceiling height may be obtained in the main part of the building by reason of the elimination of ducts between the ceiling and the floors. As a result, the present invention enables all of the advantages of the induction type of air conditioning to be had while effecting economies in installation and overall cost of the structure.

This application is a division of my copending application, Serial No. 412,217, filed February 24, 1954, now Patent No. 2,729,429, granted January 3, 1956.

Having thus described the invention, what is claimed is:

In a building and air conditioning structure, means forming a vertical shaft for the building, spaced floor supporting beams disposed externally of the shaft, a metallic load supporting floor supported by and above said beams including a plurality of longitudinally extending hollow cells defining passages for conducting air therethrough and extending transversely of said beams, vertical supply duct means in said shaft through which primary air of one condition flows, means connecting said supply duct to selected floor cells for conducting said air therethrough, outlet openings provided in said selected floor cells and an outlet structure having inlet and outlet openings being mounted on said floor and communicating with the interior of said selected floor cells and an induction inlet opening provided in said outlet structure above the surface of the floor, means provided in said outlet structure for inducing secondary air into the same through said induction inlet, said inlet having means for conditioning the secondary air passing therethrough, said difierently conditioned primary and secondary air being mixed within the outlet structure and discharged into the building.
